High temperature element for cycling conditions Kanthal® Super HT is a new electric heating element in the family of Kanthal Super molybdenum disilicide (MoSi2) heating elements, with outstanding properties for use at high temperatures, in air or oxygen, in cycling conditions. ide layer results in a much-improved service life, because the tensions are reduced between the base material and the surrounding oxide, depending on the different thermal expansion coefficients. This is of great importance, especially for elements of smaller dimensions used in cyclic conditions, where Kanthal Super 1800 and 1900 elements may be damaged by “banding”. The banding effect means that an element shatters into small pieces during thermal cycling. This is as a result of massive stresses between the oxide and the base material, once the oxide has grown to a sufficient thickness, and the strength of the oxide film exceeds that of the base material. The new properties also include a better hot strength and form stability. Kanthal Super HT offers rapid thermal cycling, which improves furnace productivity. Applications The maximum operating temperature is 1830°C (3330°F), and the element is suitable for furnace temperatures between 1500 –1750°C (2730 –3180°F) approximately. Kanthal Super HT is used in laboratory and hightemperature process furnaces, and as "a problem solver" for productivity issues at high temperatures. The special feature of Kanthal Super HT is that the growth of the oxide layer – the glaze – is much reduced, compared to Kanthal Super 1800 and 1900.
